The LT3689IUD#TRPBF is part of a series of synchronous, step-down DC-to-DC switching regulators from Linear Technology. It is configured as a buck converter with high efficiency and wide output voltage range, and is capable of supplying up to 2A of output current. The converter includes a PWM controller with an adjustable frequency operating up to 2MHz. It also features an integrated high-side and low-side MOSFET drivers to drive the external MOSFET switches of the buck converter. The LT3689IUD#TRPBF is especially suitable for power management applications requiring long battery life such as those found in handheld, battery-powered devices.

The LT3689IUD#TRPBF is a synchronous, step-down DC-to-DC switching regulator. It works on the principle of Pulse Width Modulation (PWM) to convert a DC input voltage to a DC output voltage with high efficiency. The converter utilizes two external MOSFET switches which are driven by the two integrated drivers built into the regulator. Pulse width modulation works by switching the two MOSFETs on and off at a fixed frequency, and then varying the duty cycle of the pulses, to increase or decrease the amount of power delivered to the output. This allows the regulator to provide current to the load with very high efficiency. The output voltage of the converter can be adjusted by changing the duty cycle of the pulses.

The LT3689IUD#TRPBF is a voltage regulator used in applications requiring long battery life, such as handheld, battery-powered devices. It features an adjustable frequency up to 2MHz, adjustable input voltage ratings up to 24V, and adjustable output voltage ratings up to 5.5V. Its internal current limiting and over-temperature protection ensure safe operation. The LT3689IUD#TRPBF is capable of supplying up to 2A of output current and features high efficiency ratings, so it can reduce power consumption, which in turn increases battery life. In addition, it is also capable of providing reduced power consumption on light-loads with its Pulse Frequency Modulation mode, allowing for lower quiescent current.

The LT3689IUD#TRPBF is one of the most efficient DC-to-DC switching regulators in Linear Technology’s portfolio and is suitable for a variety of cost- and space-sensitive applications. It provides users with the flexibility to adjust the input voltage and frequency, as well as the output voltage and current, providing a device that can be tailored to specific requirements. This makes the LT3689IUD#TRPBF ideal for applications such as battery-powered portable devices, as it can deliver stable, low noise and high efficiency power.
